T0 a'll whom it may concern: I

" Be it knownthat I, Canaries U; GARPENe TER, of New-York, 'in the county of --New York and in the State of New York havein vented a certain new and -useful lmprove- 'ment in Safes, and do hereby declare that,

the following is a full, ,clear, and exact description thereof, reference being had to the accompanying drawin s, inwhich Figure 1 is a front 0 ovation of a safe em bodying my inventiom't'he doorbeing shown closed; Fig. 2 is a sideelevation, partly in section, of the safe shown in 1; Fig. is a front elevation, the door being open. F s.

Fig. 8 is a view similar .to Fig. '7, theparts bei shown as they appear at the -completion tion. I p,

'lhe object of my invention has been to o the forging opera safes have been made of sheets of "metal.

either welded together or secured together as by bolts and rivets, and usually the walls of such safes have been made hollow, and

material offering more or, less resistance to heat has been placedinside the walls. Safes of this construction occasionally fail from- I one of several causes. The sheet metalwalls,

being comparatively thin, are' oceesionally penetrated by'a burglar and explosive is-in troduced, which the walls, owing to their lack of strenth, are unable to withstand. Y The bolts an rivets are a source of weak ness; they may be started by an ex lesion and may be drilled out. If the buil ing. in which the safe is placed collapses, owing to fire or earthquake, and the safe i falls to the ground, the shock isliable to distort the safe, at least enough to admit fire to its contents. The same {result may follow the Or on theground. Second, in'order to over:

come the foregoing "objections, attem ta have been made tosoconstruct safes t at' the body of the safe shall be made of a singlej iece of metal.

safe, the interior recess bemg formed by the mold. Safes constructedin .this manner areobjectionable, however, because; blow holes and other defects fre uently o.ccur in the so Safes have been constructed; 1 1n this manner by casting the body of the;

metal," both inplaces w ere they can be seen, and also concealed beneath the; surface ef the metal. 'Those blow holes which ean be seen result in the rejection of a large iiumberof the castings made for this purpose. '?l3low"" holes of apparently insignificant pro ortions" are frequently much larger within t e body, of the metal than would appear at the surface 'of the casting, and the safe may thus be fatallyweak'even though it has only an parently trifling blow ho e on the surface.

I those safes where no blow holes can beseen on'the surface, and which are accordingly put into use, there are frequehtly blow holes andfissures within the body of the 'metal which render the safe weak, but which, being invisible, do not-prevent the: casting from being put into use. For these reasons the cast sales as heretofore constructed are not entirely satisfactory.

It hasbeen the object of m invention to l overcome the objections to hot of the above described classes of safe construction. ,Not-

withstanding the eat thickness of the walls of a safe compare with the size of the body thereof, I have conceived the-making of a.

safe in a" single piece by forging, a roce's's b which I am enabled to get a safew ose wa s I are thoroughly homogeneous and without defects of any kind,- and a safe of .much greater strength than is possible to obtain by casting. g In ca first obtain a heavy plate of stage such as armor plate. This plate 10' I place over a die,-

the die consisting pfeferably of sections 1 1 and 12,which-form etween them a recess 13- of the shape which it is desired the safe body o s to have. I his recess I prefer to form tapering in a downward direction, although it may have any desired shape.

conicaL' The two'sections of the 'die are united by bolts 14 so that the die .may be separated if desired to release the forged safe I It ma be circular or rectangular, and' cyllndrica or frustorig-my inventioninto racticeI d 1Q body; The die may, however, be formed in d oft e die. lo -moved from the die, the'die sections may, if desired, ,be forged on the body,

' others the following advantages: The bo y a. single piece if desired. dieis seated beneatha hydraulicpress, steam hammer or other similar device; lTh'epress jor'hammerf 1 carries a plunger v15 of the'sha '5 to form the ingericgl of p er 15 is pre era tapering to eu-v able it 'which it e'safe body;

It may, howefver, have no taper 'lfi forging the safe the late 16, of' .10- armor plate from which t safe forged, is laid over the die 12, and .the plunger 15 orced down by the press or hammeriuntil the late com letely conforms to the interior he forged safe body isnow rev seplarated if necessary. v he next step is referably the turning or formin of the rab ts or ooves 17 in the body 6 thesafe' to receixe t e corresponding 20 shoulders 18-on the door. --The members 19 of the hinge 'which are to beonthe body but prefer to make them so them as by bolts 20." e door 21 is prefer- 25' ably formed of a sihgle'forging, and its hinge 'member '22 'is pre erably formed integral therewith. The door 'is provided with bolts- 23, or other form of'lock, as maybe desired. The particular formof lockis not essential.

Thesafe body is preferably mounted upon a wheeled base 24 in any desired manner as-bybolts passing into'the base from within the body.- Shelvin 25 of any desired construc-.

tion is rovide within the safe.
